Thanks! It fixed now. You can try to remove contrib-pysite package, PlatformIO Core will install default which does not work. However, it should automatically build a new package on your machine.

Still getting the same error on RaspberryPI 3B+ with Raspbian 9.11.
ImportError: /home/pi/.platformio/packages/contrib-pysite/cryptography/hazmat/bindings/_constant_time.abi3.so: cannot open shared object file: No such file or directory

I tried to upgrade via pio upgrade --dev. There were a lot of packages being installed by pip and some warnings aka WARNING: Target directory /home/pi/.platformio/packages/contrib-pysite/cryptography already exists. Specify --upgrade to force replacement.

After that on pio remote agent start there was another error:
ImportError: /usr/lib/arm-linux-gnueabihf/libssl.so.1.1: version `OPENSSL_1_1_1' not found (required by /home/pi/.platformio/packages/contrib-pysite/cryptography/hazmat/bindings/_openssl.abi3.so)
